Monitoring and control of the NEPTUNE data net- works will be implemented using the simple network monitoring protocol (SNMP) served from network supervision work stations located on shore. SNMP clients will also be included in the power distribution system components to centralize and standardize all monitoring and control functions. SNMP clients can also be incorporated into the science instrument inter- face to simplify user level supervision. These high level system monitoring and control systems will function when the data communications backbone systems are operational.
